ngxtop<\/strong>\u00a0is a free open source, simple, flexible, fully configurable and easy-to-use real-time\u00a0top-like monitoring tool<\/a>\u00a0for nginx server. It gathers data by parsing the nginx access log (default location is always\u00a0\/var\/log\/nginx\/access.log<\/strong>) and displays useful metrics of your nginx server, thus helping you to keep an eye on your web server in real-time. It also allows you to parse Apache logs from a remote server.<\/p>\n

How to Install and Use Ngxtop in Linux<\/h3>\n

To install\u00a0ngxtop<\/strong>, first you need to\u00a0install PIP in Linux<\/a>, once you have\u00a0pip<\/strong>\u00a0installed on your system, you can install\u00a0ngxtop<\/strong>\u00a0using following command.<\/p>\n

$ sudo pip install ngxtop\r\n<\/pre>\n
Monitor Nginx Server Requests<\/h4>\n
Now that you have installed\u00a0ngxtop<\/strong>, the easiest way to run it is without any arguments. This will parse the\u00a0\/var\/log\/nginx\/access.log<\/strong>\u00a0and runs in follow mode (watch for new lines as they are written to the access log) by default.<\/p>\n
$ sudo ngxtop\r\n<\/pre>\n
